Transcript of Introduction to AP Biology

What is Advanced Placement Biology?Curriculum Framework4 Big IdeasBIG IDEA #1The process of evolution drives the diversity and unity of life.BIG IDEA #2Biological Systems utilize free energy and molecular building blocks to grow, to reproduce and to maintain dynamic homeostasis.BIG IDEA #3Living systems store, retrieve, transmit and respond to information essential to life processes.BIG IDEA #4Biological systems interact, and these systems and their interactions possess complex properties.-- Theodosius DobzhanskyMarch 1973Geneticist, Columbia University(1900-1975)"Nothing in biology makes sense except in the light of evolution."2007-2008AP BiologyArchaeaBacteriaEukarya7 Science PracticesFrom AP Biology: A Summary of Course Revisions13 "Official" Labs TextbookTHE EXAMPREPARING FOR THE EXAMi.e. COMMON CLASS ACTIVITIESDoing lab workDiscussion!Writing....and writing moreAsking QuestionsPractice Test TakingMaking modelsUsing TechnologyReading, a lot!Analyzing DataUsing mathematicsWhat is "AP"?pursue college level coursework while still in high schoolearn college credit or advanced placement (exempt you from taking a required class in college & bumps you up to taking a more advanced/specialized class)demonstrates to college admissions officers that you want to challenge yourself--valuable, even if you don't do well in the courseQuality assurance: Audit process ensures AP class aligns with college standardsDemonstrate mastery by taking the college-level assessment>90% of 4-yr colleges & universities in the US award college level credit or advanced placement (or both) for successful exam scores.www.collegeboard.com/ap/creditpolicyResearch consistently shows that students who score a 3 or higher on AP exams typically experience greater academic success in college and have higher rates of graduation than otherwise comparable non-AP peers.Scoring:5-4-3-2-15 = highly qualifiedequivalent to scoring an A+ or A in college level class.4 = well qualifiedequivalent to scoring an A-, B+ or B in a college level class3 = qualifiedequivalent to scoring a B-, C+ or C in a college level class.Less focus on recall of factual detailMore focus on enduring conceptual understandings and the content that supports them.Inquiry based learning will help you develop essential reasoning skills.Equivalent to a 2-semesterintroductory biology course.Must do 2 inquiry based labs per Big IdeaWill spend >25% of class time doing labs and working on the 7 science practices/building reasoning skills.3 hours2 sections--Multiple Choice (90 minutes) & Free response (90 minutes)Each section is weighted equally (50% of score for M/C; 50% for FRQ)May use 4 fn calculator with square root ONLYformula list will be suppliedsex hormones influence phenotypeglowfish are transgenic animalsa jellyfish gene gives the zebrafish a new phenotypethe central dogma of molecular biologyalbinism--what happens when the "code" changesfight or flight response is alive and wellGeological and meteorlogical events affect living organismskudzu, an invasive plant, alters ecosystemsmany insects and plants have co-evolved so as to depend on one another--many plants rely on insect pollination to sexually reproducewater molecules and these phospholipid molecules have different properties and so interact in discrete waysDNA molecule-a molecule of code--the code for building proteins, the workhorse molecules in cellsEvolution explain diversity & unityEvolution allows us to explore "degrees of relatedness" and patterns of ancestryCellular structure can be explained by historical, evolutionary eventsMany lines of evidence, including a universal genetic code for all of life's diversity support the theory of evolution by natural selectionThe tools of molecular biology allow us to "see" evolution at the molecular level--patterns of relatedness among organisms can be explored at the level of proteins & DNAThe great diversity among life's many organism can be explained via the theory of evolution by natural selection.Mathematical models give us another tool to test our ideas about the process of natural selection.E.I.E.I. OoooooooA building block (glucose) for making an energy storage molecule (starch)."THE" energy molecule that virtually all of life uses as its energy "currency": ATPEnergy transfer can be seen at the level of communities and ecosystems as this graph shows how energy transfer from hares to lynx affect the population sizes of each.Energy transfer within the muscle cells of this leopard allow her to reach record speeds for mammals.
